Transfer Operators and Modular Forms -- lecture 4

This is the fourth lecture of the course "Transfer Operators and Modular Forms". In this lecture, we study how the automorphicity of eigenfunctions of the Laplace operator affects the corresponding hyperfunctions on the boundary of hyperbolic plane. Addiotionally, we (at least formally) introduce the period functions and show how the three-term functional equation holds.
